Winchester Unprimed Brass Rifle Cartridge Cases - .338 Lapua 20/box undergo a strict manufacturing process that starts by using high-quality materials and superior smelting, making them a popular choice among game hunters and competitive shooters. As with all Winchester cases, the company's skilled professionals always focus on quality control to meet exact specifications.

In particular, solidity, hardness, and grain structure are looked at during the manufacturing process. Designed for a .338 Lapua Magnum, the cases may not have perfectly rounded heads because of shipping or manufacturing, so they need to be sized, deburred, and chamfered prior to reloading.
